Some time ago I started to feel a need to have a bench power supply. Not laboratory-grade, but something that can deliver both some volts and amps. Of course with overcurrent protection. Aliexpress is full of such a power supply units and at the end, I've decided on Yihua PS-3010DF with 30V voltage and 10A max current.

Yihua PS-3010DF power supply

My initial thoughts are:

  • On the outside, it looks and feels pretty solid
  • You can power a drone on a workbench from it. Even with motors running!
  • Current limiting works and it can replace a smoke-stopper
  • Too bad you can not set max current before turning this thing on
  • It only shows current current, not the limit
  • USB is a nice touch
  • Teardown in a few weeks :)
